2x + 24 = 9x - 39= 2x + 63 = 9x= 63 = 7x= x = 9

it equals 13X.

2x + ? = 9x9x - 2x = 7xso...2x + 7x = 9x

It is 9x

2x+3=9x-2x -2x3=7x/7 /73/7=x

2x+3=9x =>3=7x =>3/7=x

2x + 5x - 1 = 9x 7x - 1 = 9x -1 = 9x - 7x -1 = 2x -1/2=x

2x+3 = 9x 3 = 9x-2x = 7x 7x = 3 x = 3/7

X= -2

2x+5=11 2x=6 x=3

2x + 3 = 9x Subtract 2x from both sides: 3 = 7x Divide both sides by 7: 3/7 = x

answer is 4 7x+19=-2x+55 +2x +2x 9x+19= 0 55 -19 -19 9x = 36 9 9 =4

If RS = 23-2x, ST = 9x -5, and RT = 39, find RS.

7x + 19 = -2x + 55Add 2x to both sides:9x + 19 = 55Subtract 19 from both sides:9x = 36Divide both sides by 9x = 4

9x+6 = 7x+18 9x-7x = 18-6 2x = 12 x = 6

2x + 9x simplified would be 11x

180=11x+9x. 180 = 20x. 18=2x. 9=x.

9x-5x-2x = -4 2x = -4 x = -2

9x=2x+14 subtract 2x from both sides you have 7x = 14 left. divide each side by 7 x=2

2x + 3y = 9x = 3, y = 1 therefore 6 + 3 = 9

2x + 3 = 9x start by bringing the 2x over- minus it from both sides 3 = 7x divide 7 by on sides x= 3/7 x = .4285714285714 repeating.

9x-4 = 7x+8 9x-7x = 8+4 2x = 12 x = 6

2x2 + 10 = 9x 2x2 - 9x + 10 = 0 (x - 2)(2x - 5) = 0

x + 2x + 6x = 9x
